2-phase stepping motor driver RB2302

**RB2303 is a high performance, low price micro-step driver,voltage range from DC12-30V, single power input. It can match 4leads\ 6 leads or 8 leads two phase hybrid step motors whose rated current under 2.0A flange size range from 28mm-57mm. Owe to bipolar constant current chopping circuit, the motor can run smoothly and hardly has any noise;

Rising the voltage can greatly improve high speed performance and output torque of the motor. Once the pulse stops for 300ms,the phase current will automatically cut by half, which can reduce chances of overheat.

Two group 8 channels constant angel and constant torque subdivision. Highest subdivision:128

Special control circuit to reduce the noise

Upmost response frequency amounts to 800kpps

Once the pulse stops for 300ms, phase current automatically cut by half

Bipolar constant current chopper control

Photocoupler isolated input/output

Drive current from 0.1A/phase to 2.0A/phase

Single power input, voltage range from DC12-30V

Overheat prortection, Overcurrent &TSD protection;

Once the temperature over 170°C, the protection will turn on

Dimension 105mm×60mm×27mm;Net weight:0.160k g
